Abstract
A method, apparatus, and non-transitory computer readable medium for video tone mapping. The method includes a target display receiving a quantized video generated by a master display, the quantized video being mastered for a first range of luminance values associated with the master display; receiving metadata from a tone mapping curve parameter extraction, the metadata comprising at least one maximum value of a luminance parameter of the quantized video as mastered for the first range of luminance values; and de-quantizing the quantized video to produce a de-quantized video. The method also includes at least one processor of the target display applying a tone mapping function defined by a normalized Bezier curve to the de-quantized video; and generating, based on applying the tone mapping function, a tone mapped video mastered for a second range of luminance values associated with the target display.
